Alang, sounds exciting brother. I haven't had time to read all the comments so I'll just put my two cents. It sounds like God has given you a little encounter to go with and possibly opened a door for a future relationship? My advice would be to be cool, patient and seek the Lord on this one allowing him to present the opportunities to meet her again. I think when it comes to dating as Christians, there's always this strange sense as though God disapproves when it's actually him who guides most Christians together and if he has chosen this girl for you, I can assure you the opportunity WONT pass you by brother. Just be cool and enjoy it, you'll know what to do and say when the time comes. You always seem to me to be a great guy and judging by your comments and opinions, you have a very committed heart toward the Lord so, God will honour your life in him and grant you the desires of your heart.
